Title: Dual purpose wood peeling and length cutting machine - has length scanner linked to additional blade on second slide carriage
IPC: B27L5/00
Filed: 1977-02-21
Abstract: The wood peeling machine, esp. for bark stripping from tree trunks, cross-cuts the material into set lengths.

Title: Photographic type composing machine
IPC: B41B27/02
Filed: 1978-02-16
Abstract: The machine provides access to a relatively large number of different characters located on relatively large spinning discs or drums. The characters are located in arrays such as concentric rows on a disc. A plurality of lenses is mounted on a lens carriage, and one or more light sources is mounted on a flash-lamp carriage. Character spacing is determined by motion of the lens carriage and/or the lamp carriage. Array selection is performed by motion of the lamp carriage, and/or motion of the lens carriage. Composition of lines or columns of characters taken from a relatively large number of different arrays, such as would be the case in type composition using Chinese ideographs, is speeded considerably by controlling the order in which the characters are projected so that the lens carriage need not reverse its direction of motion during composition of a line. A simple mechanism is used to change lenses for size changes by the selective use of stops at the ends of the travel path of the lens carriage. Two discs or drums can be used alternatingly to increase the number of characters available. A simple attachment is provided for composing long lines of enlarged characters for composing headlines and the like. This avoids the necessity of providing a separate headlining machine. Another simple attachment is provided for inserting Pi characters. This attachment makes use of the lamp carriage and drive mechanism in selecting the Pi characters for projection. A method which is especially useful in economically producing large matrix discs is described. An economical "floppy" or flexible film disc also is described. A system and method are described for electronically detecting base-line and spacing errors in the characters on the character matrix, storing the errors, and correcting the errors electronically during projection of the characters onto the photographic film.

Title: Method for the sub-terranean generation of heat.
IPC: F24J3/08
Filed: 1982-08-11
Abstract: Subterranean generation of heat as a source of energy optionally accompanied by the production of minerals. In subterranean formations of minerals that are capable of undergoing an enthalpic degradation, such degradation is artificially accelerated by several orders of magnitude. To this end a bore hole is drilled down to the desired formation and accelerated enthalpic degradation is made to occur by a suitable ignition. For the extraction of energy the bore hole is flushed with water and the resulting steam is withdrawn. In one embodiment, one and the same bore hole is used for charging water and withdrawing steam. In another embodiment the bore holes are arranged pairwise, one bore hole of each pair serving for ignition and introduction of water and the other serves for the withdrawal of steam. After the formation has cooled down to the point where steam is no longer generated to any significant extent it is possible to continue with flushing and subjecting the reemerging aqueous phase to an operation or sequence of operations for the recovery of minerals therefrom.

Title: Controlled operation grinding roll refiner for chocolate.
IPC: C09D7/80
Filed: 1984-05-31
Abstract: A refiner for mixtures and suspensions having a non-Newtonian rheological characteristic, such as chocolate, which comprises a plurality of power driven refining rollers, and a means of changing the pressure thereof on the respective supports, wherein a means is also provided which is effective to change the actual crowning of the rollers, or the effect of an equivalent crowning, as well as a means of changing the speed of said refining rollers.
